WATER-ELEVATOR.

To all whom. 'it may concern:

Be it known that I, JAMES L. 'nar, a

citizen of the United States. residingr at Kewanee` in the county of Henriv and .State of Illinois, hare invented a new and useful 'ater-lllevator. of which the. followinior is a specification.

This inven'ion relates to that class of water elevating;` apparatus characterized hy a .pair of submerged, or partly sulnuerged tanks. into which the water Hows. and from which itis aiternately discharged by couipressed air, the air acting as a. piston to drive the water to its destination, and theI entry of the air into the tanks being groverned by a filmt-controlled Valve mechanism.

The object of the present invention is to siiuplifvtlze apparatus, and to render the sante. more etieient in operation, and also to )rovide an improved torni of valve inet-han tsm by which a waste of air is effeetually prevented.

lith the foregoing objet-ts in View, the. invention consists in a novel construction and arrangement ot' parts to he hereinafter described and claimed. reference being had to the drawing r hereto annexed forming a part cf-this specification. in whirli- Figure 1 is a vertical .sectional view of the apparatus. Figs. L). and 3 are sectional details of the valve hereinafter described, showing the same in bdittereut positions.

In the drawings. 5 and 5 indicate a paii oftanks in whieh'the pressure ot' the air ir; brought to hear on tho water, the air acting as a piston to drive the water. The tanks are, sulinierged, or partljvv submerged, in the water to be elevated, and the latter enters the tanks through inlets in the bottoni thereof, said inlets bring controlled h v inwardly opening check valves t3 and t3,` F rom each tank leads a discharge. pipe 7 which carries the water to its destination. The discharge pipes connnnuicate with the tanks close to the hottom thereof, and are prot ided caeh with a check valve 5.

At tl is indicated an air cylinder which is lmfated outside the tanks. and is in conunnnication therewith. a pipe it) leading from the cylinder to the tank 5 and a pipe l0* to the tank 5*. ln the c viiuder t) works a pair of pistons 1l and it which are connected hy a stem 12 so as to more in unison. Between these pistons the cylinder is provided with an exhaust. port Il. Coni-pressed air is snpplied to the cylinder from a suitable source Patented Apr. 19, 1910.

by a pipe 14 entering one end of the cylinder, and a pipe. la entering the opposite end thereof. These pipesare supported by standards- 15 rising.:` from the tanks, and by vhch a support for the cylinder 9 is also c ia The

pipes

14 and 14 lead to a multiplevalve easing 16 to hielt is also connected a i pipe 17 leading to the source of supply. l This pipe 1i' enters the valve easing' at a point midway between the points of entry of side ot the valve casing, equidstant from the ponits of enti) of said pipes 1-t and 14.-,

The casing,r 1G contains a rotar); ra re L9 having on one side a passage 2t) and an intermediate passage. 21, and on the other side a passage. Q0"- and an intermediate passage 211. The purpose of this arrangement of Jassages will he understood from the following description of 'the operatien of the apparatus.

Pig. 1 of the drawings shows the position of the various parts` when the air is from the tank 5R. The passage '20 of the iale 1E) establishes eonnnunuaition between therefore enters that en( of the cylinder 9 l to which said pipe 14 is conneeted,.and tlows through the pipe l0 into the tank 5. pressure of the' air on the contents of the tank forces the saine. out of the tank through the pipe 7, the cheek valve (l closing. The

the pipe 10, into the space hetween the pisl tons 11 and 1l, and out, (if-the port 13 to the atmosphere. The end et the cylinder 9 which is, entered by the pipe 1t' is also open to the atmosphere through the pipe 14 and l passages QCP- antl 2P. By thus opening the l 'space hetwecn the piston I l and the adjal cent end of the cylinder t) to.the atniostphere, the pressure in said space is enahted to escape, and is therefore not4 retained in the cylinder to oppose the movement oi' the piston ll as it travels in this direction at tho beginning of the herein-deserihed operation, in order to r-stahlish communication het wecn the cylint'ler Sl and the tank 'lhe valve 19 operated by a lever 22 to eac-h end of which is connected by means of a chain or other snitahle tiexihle eonneetion 23 a rod 24. Une of these rods extends into the tank 5, and the other rod into the tank 5*. On

passing into the tank 5, and exhausting the pipe 1T and the pi e llt, and `the air' the

pipes

14 and 14% and on the opposite.

are outlet ports 15:- and 1S to the atmosphere.

'ne l tank 5 is eni'itt', the air exhale-tiner through the rod within the tank 5 is mounted a float .25, and on the rod within the tank 5a is pulls that end of the lever Qi. to which its rod Qt is connected downwardly, whereupon the p'osition of the valve 19 is reversed, so that the position of the pistons 1l and 11a is reversed. With the said valve in reversed position, air enters the tank 5 and exhausts fronr the tank 5, whereupon the water is forced out et' the tank 5a, and it enters the tank 5.

The mechanism herein described is devoid of complicated parts to get out of order, and it therefore reliable in operation. The valve 1S) is designed so as to cut ott' the air supply before the tark to which the air is llowin r is entirel)v emptied, whereby .t great saving ofair is vliet-ted.

'l`he air llowingr to the-tank 5 is cut ottl as soon as the passage 20 clears the inlet port of the alve casing t6, and thereafter, and until the position ot' the valve is entirely reversed, the air in said tank operates expansifely lo expel the water therefrom. 'This will be evident from an inspection of Fig. 2 `which shows the intermediate position of the valve. During this position of the valve, thc exhaust from the tank is not cui oil', but takes place'through the pipe 10, cylinder l2, and port 13.

In a water elevator, a pair of tanks having inlets and outlets, a tluid pressure and cmnniunicating with the tanks, a valve workinglr in the c vlindtr` and alternately establishing eonnnunication between the cylinder and the tanks, a valve eonlrollin;r the flow to the cylinder and having its pas sages arrangwlto eut oll the lluid piessure supply to the cylinder before the tank which is in eonnnnnicat'ion therewith is emptied. the course of the lluid pressure in itsl travel to the tanks being through the lasty n n-utioued valve and the cylinder, and lloat-controlled means for operatingr the last inen- -t ioned valve.
